Infrared-sensitive color developing composition, lithographic printing plate precursor, plate making method for lithographic printing plate, and infrared-sensitive color developer

A lithographic printing plate precursor comprising on a support:

• an image-recording layer including a compound represented by Formula (1), as Component A;
• a binder polymer, as Component B;
• a polymerization initiator, as Component C;
• and
• a polymerizable compound, as Component D,
• wherein, in Formula (1), each of R1 and R8 independently represents an alkyl group, each of R2, R3, R4, R5, R6, and R7 independently represents a hydrogen atom or an alkyl group, R4 and R5 may be linked together and thus form a ring, each of Q1 and Q2 independently represents —NR0—, —S—, —O—, or a dialkylmethylene group, R0 represents a hydrogen atom, an alkyl group, or an aryl group, each of T1 and T2 independently represents an aromatic ring or a heterocyclic aromatic ring, X1 represents a divalent linking group, A− represents a counter anion, each of R9, R10, R11, and R12 independently represents an alkyl group or an aryl group, each of R13 and R14 independently represents a hydrogen atom or a monovalent substituent, R13 and R14 may be bonded together and thus form a ring, each of R15 and R16 independently represents a monovalent substituent, and each of n1 and n2 independently represents an integer of 0 to 3.
